Abstract

This paper focuses on the development of a system that improves the convenience of foreign language learning and enhaces the learning ability of the target language through the use of IT devices. In addition to the basic grammar, the importance of pronunciation and intonation have somewhat crucial effect in everyday communication. Pronunciation and intonation of English are different according to the basic characteristics of a native language and these differences often cause problems in communication. The proposed system distinguishes acceptability in English communication process and requests the correction in realtime. The proposed system minimizes system intervention by collecting various voice signals of foreign language learners and setting that can be considered as acceptable threshold points. As a result, the learner can increase the learning efficiency with minimal interruption of the utterance caused by unnecessary system intervention.

본 논문은 IT 기기의 활용을 통해 외국어 학습 편의성을 제공하여 외국어학습에 대한 학습력 증진의 실효성을 높여주는 시스템 개발에 중점을 두고 있다. 다양한 환경에서 의사소통의 기준으로 큰 역할을 하고 있는 영어를 학습할 때 기본적인 어법 외에도 발음과 억양의 중요성이 의사소통에 큰 역할을 한다. 발음 및 억양은 사용하는 모국어의 특성에 따라서 다르게 나타나고 이러한 차이로 인해 의사소통에 문제가 발생하는 경우가 다수 존재한다. 제안 시스템은 학습자의 모국어 발음 및 억양에 대한 정보를 바탕으로 영어 의사소통 과정에서 수용가능한 발음과 억양을 구분하여 시스템의 개입이 필요하다고 판단되는 경우 수정 및 보완을 요청하여 학습이 이루어지도록 도움을 주는데 목적이 있다. 제안 시스템은 학습자들의 음성신호를 수집하여 수용가능한 임계점을 설정하여 시스템의 개입을 최소화한다. 그 결과 불필요한 시스템 개입으로 인한 발화의 중단이 최소화되어 효율성이 증가할 수 있을 것이다.
